At around 1.45am last Wednesday, a marked Thames Valley Police car was involved in a collision with Mr Williams in Wokingham Road. He died at the scene and a police officer was also injured in the collision and taken to hospital with minor injuries. He has since been discharged.

The IPCC was notified shortly before 3am on the Wednesday and an investigator was sent to the scene. A further investigator attended the post incident procedure, where officers involved provided their initial accounts. The IPCC said as is standard practice the officers were warned not to confer.

IPCC investigators also requested a neighbouring force’s road traffic investigation unit attend the scene to conduct an examination. That examination concluded on Wednesday and the police car involved in the collision was removed from the scene and is undergoing further forensic tests.

The car was also fitted with onboard data recorders, and the information on them has been secured and is being analysed, say investigators.

CCTV from the area has also been secured and IPCC investigators have been conducting house-to-house enquiries to identify potential witnesses and other CCTV.

A post mortem has been conducted, and an inquest is yet to be opened into Mr Williams' death.

IPCC associate commissioner Guido Liguori, said: "I would like to offer my condolences to Aston's family at this difficult time. We have met with his family to explain our role, while our investigators have made good progress in recovering a range of evidence to ensure that our investigation is able to provide them with a comprehensive account of what happened.”

Meanwhile, flowers and cards have been left at the scene of the incident, paying tribute to "Aston, my world", "It's not good bye boo boo, it's see you soon!" and "you are my world, my soul mate, my sexc man".
